射频前端 5GHZ 27dBm Gain 30 dB typ.
The SE5012T is a 5GHz front end module offering high linear power for wireless LAN applications. It incorporates a power detector for control of the output power. The SE5012T offers a high level of integration for a simplified design, providing quicker time to market and higher application board production yield. The device integrates the input match, inter-stage match, a temperature compensated, load insensitive power detector with 20dB of dynamic range, a 3.8GHz notch filter, a T/R switch and LNA. For wireless LAN applications, the device meets the requirements of IEEE802.11a and delivers approximately 17dBm of linear output power at VCC=3.3V or 21dBm at VCC=5.0V. It also features a low linearity mode control to reduce current consumption at low power modes. The SE5012T integrates the reference voltage generator, allowing for a true 1.8V CMOS compatible digital EN enable function to turn the power amplifier on and off.
